The Opportunity

Prompts as inline strings cause staging/prod drift and quality degradation nobody can trace.

Original Signal

I updated my system prompt and my app completely changed behavior. I have no idea what version was working before and no way to roll back. I'm just guessing at this point.

Score Breakdown

10/15
Demand3.0/5

How urgently people need this solved and how willing they are to pay for it. Based on complaint frequency and spending signals across platforms.

Market Gap3/5

How open the market is. A high score means few or no direct competitors, or existing solutions are overpriced and underdeliver.

Build Effort4/5

How quickly a solo developer can ship an MVP. 5 = weekend project with standard tools. 1 = months of infrastructure work.

Existing Solutions

PromptLayer logs prompts and responses but doesn't have version control or diffing. Langfuse has some versioning but it's complex and not focused on the rollback use case.

Willingness to Pay

Teams building AI products pay $20-49/month for prompt management tools; a Git-style version control focused purely on prompts would charge $19-29/month.
